Getting “Deadlock found when trying to get lock; try restarting transaction”

Question

07:43:33,400 WARN  [org.         


        

Answer 1

When you face this kind of error "deadlock detected". You should inspect your queries execution and verify if two or more concurrent transactions can cause a deadlock.

These transactions should acquire database locks in the same order in order to avoid deadlock.
